A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?

A. Store the dentures in a dry denture cup on the bedside table after cleaning.: Dentures should not be stored in a dry cup as this can lead to drying out and warping of the dentures. They should be stored in water or a denture solution to keep them moist.

B. Place a towel in the sink when cleaning the dentures.: This is correct. Placing a towel in the sink is a safety precaution to prevent dentures from breaking if they are accidentally dropped while being cleaned. It also helps prevent damage from impact with hard surfaces.

C. Remove the lower dentures before the upper dentures.: There is no specific order required for removing dentures, as both upper and lower dentures should be removed carefully and cleaned.

D. Use a circular motion to cleanse the biting surface of the dentures.: A circular motion is not the best technique for cleaning dentures. Instead, the dentures should be brushed gently with a soft toothbrush, focusing on cleaning all surfaces, including the biting surfaces, using a back-and-forth motion.

A. Assign clients to the remaining staff is not the first action. The nurse should address the suspected impairment of the staff member before assigning clients to others.

B. Call the supervisor to ask for another nurse is not the first action. While notifying the supervisor is important, the nurse should first ensure that the impaired nurse is removed from direct client care to prevent any potential harm to clients.

C. Remove the nurse from the client care area is correct. The first priority is to ensure that the nurse who may be impaired is not caring for clients to ensure client safety.

D. Document objective findings about the situation is important but not the first step. The immediate priority is ensuring the safety of clients by removing the nurse from the care area. Documentation can follow after ensuring client safety.
